FEATURES & BENEFITS
- CALCIUM HARDNESS INCREASER is used to raise calcium hardness in swimming pool water
- Low calcium hardness causes pool water to be corrosive and may result in staining, etching or distorting of the pool's finish
- Plaster etched by low calcium hardness will become abrasive and uncomfortable for swimmers
- Rough plaster increases algae problems and makes cleaning more difficult
- Calcium hardness in pool water should be maintained in the 175-275 ppm range
- Never allow calcium hardness to remain below 100 ppm
- Add this product directly to pool water by scattering it over the water surface. Do not predissolve this treatment as heat is generated when this product contacts water
